The 15-inch MacBook Pro with Retina display, unveiled on June 11, 2012, was Apple's "next generation" professional laptop, featuring a radically thinner and lighter design, all-flash storage, quad-core Intel Core i7 processors, and an ultra-high resolution display.
Key Features and Connectivity
Radical Redesign: The new unibody design was 25 percent thinner than the previous MacBook Pro models and eliminated the optical drive to achieve its thinness and low weight.
Retina Display: Heralded as having the world's highest resolution notebook display at the time, it featured over 5 million pixels for incredibly sharp text and graphics.
All-Flash Architecture: The use of flash storage exclusively contributed to the laptop's speed, durability, and compact form factor.
Ports: Apple introduced new connectivity options while removing others. Ports included:
MagSafe 2 power port
Two Thunderbolt ports (up to 10 Gbps)
Two USB 3.0 ports (up to 5 Gbps)
One HDMI port
One SDXC card slot
Headphone port
Missing Ports: This model did not include a built-in Ethernet port or a FireWire 800 port; however, Thunderbolt adapters were available for purchase separately.
